Fed up of seeing him playing the bad guy in so many films. Sick of the sound of his voice, almost.

If he is used, cast someone with hair who either directly or indirectly is caused to look the way he does by actions against Quantum and and then becomes a symbol for Quantum the same way Bond is a symbol for his ethos.

Character motivation has been a big factor since the reboot keep it that way and just enlarge the mythos.

But no to Mark Strong. Repetition this may be but he has played somany bad guys giving essentially the same performance each time that I totally dread ever seeing him play bad again.
